ADJUSTABLE CHAIR.

Specification of Letters Patent.

Patented May 29, 191 7.

Application filed April 8, 1916. Serial No. 89,951.

To aZZ whom it may concern Be it known that I, GEORGE HENRY SAU'rmu, acitizen of the United States, residing at Chicago, in the countyof Cookand State of Illinois, have invented a new and useful Improvement inAdjustable Chairs, of which the following is a specifi cation.

The object of my invention is tomake an inexpensive serviceable chairthat may easily be adjusted to vary the height of the seat to suit therequirements of diiferent sized persons and particularly to be valuableas a high chair for children in which case the seat may easily beadjusted downward as the child grows. The common high chair soon becomestoo high for the child and then the ordinary chair is too low, during aperiod of a childs development. With my invention a single chair willanswer for the child as it grows. Further hotels and restaurants can usemy invention and meet all requirements of children with a single designof chair which is a desideratum.

Various different designs of adjustable chairs have been made but noneof them of which I am aware meet the requirements as well as mine.

Reference will be made to the accompanying drawings in which Figure 1 isa side elevation of my chair. Fig. 2 is a plan View at the level of thetop of the chair seat, the back being in section.

. Fig. 3 is a section of one front leg on line e e of Fig. i.

Fig. 4; is a side sectional elevation through the top portion of one ofthe front legs.

Fig. 5 is a front elevation of the top of one of the front legs.

Fig. 6 is a view on theopposite side from that of Fig. 5.

In the drawings 1 indicates any ordinary chair seat here shown as beingmade of wood. 2 indicates the back rails similar to many chair designsbut in my case I provide central straight vertical portions 3 on theback rails where the seat joins them.

4 indicates the front legs on top of which there are telescoping sockets5' sliding over the tops of the legs l and secured to the seat 1.

Fastened to the chair seat at the corners at the back are two clips 6which embrace the back rails 2 in sliding contact with the verticalportions 3.

The straight portions 3 are provided with holes 7 adapted to be engagedby locking bolts 8 passing through suitable holes in the inside flangeportion 9 of the clips 6.

-On the locking bolts 8 there are secured linger clips 10. The bolts 8are hinged at 11 to levers 12 hinged at 18 to lugs 1i on the sockets 5and the lower ends 15 of the levers 12 pass through slots in the back ofthe socket 5 and engage notches 16 in the front legs 4. Springs 17 holdthe levers 12 normally in a locked position and at the same time holdthe bolts 8 in a locked position in the holes 7 of the back rails.

Slots 18 in front of sockets 5 engage screws 19 in the legs and thusprevent the pockets 5 from being lifted clear off the front egs 4t.

In adjusting the chair seat downward to a lower position as indicated bydotted lines in Fig. l the operator stands in front and places his handson the edges of the seat. at the middle of the sides and over the clips10 and with the ends of his fingers on the clips 10 he unlocksthe boltsand levers and holds them unlocked while he pushes the seat down to anew desired position.

In adjusting the chair'upward the operator stands at the back and leanshis body over the back and in that way holds the chair down while withhis hands he releases the bolts and levers as before described and liftsthe seat as desired to new positions.

The adjustments are easily and quickly made and may be accomplished whenthe chair is occupied by a child which is a desideratum.

What I claim is:

1. In a device of the class described an adjustableseat adapted to beraised and lowered and locked in different positions, and guided on thechair legs by sockets tglescoping the front legs and clips embracing therear legs; with means on each side of the chair for simultaneouslylocking the sockets and clips to the legs.

2. In an adjustable chair a seat provided with sockets that telescopeover the tops of the front legs and clips that embrace the back legs,notches in the legs adapted to re ceive locking members, locking levershinged to the sockets of the front legs and held into engagement withthe notches by springs,

locking bolts hinged to the levers and adapted to be actuated in lockingthe seat to the rear legs simultaneously with the action of the lockinglevers.

3. In an adjustable chair an adjustable seat adapted to be raised orlowered by sliding contact With the chair frame, clips and socketssecured to the seat and embracing the chair frame, locking devicesmounted under the chair seat at the sides thereof and adapted to locksimultaneously the front and rear of the seat on the, same side.

4. In a chair of the class described an adjustable seat held in positionin the chair frame by sockets and clips adapted to permit verticalsliding contact With the chair frame, locking levers mounted at one setof legs and locking bolts at the other set of legs and connected tooperate together in releasing or securing the seat in the chair frame.

5. In a chair of the class described, an adjustable seat adapted to beadjusted in vertical sliding contact in relation to the V chair frameand back, and held at all four corners of the seat, sockets or clipssecured to the seat and adapted to engage the chair from all fourcorners, the back legs of the chair forming the back frame as Well asthe legs and having inclined portions at the top and bottom and straightportions at the middle Where the seat is secured, With means for lockingthe seat in different positions for height.
